Stomach cancer patients can eat mango in moderation if they are not allergic to mango. Stomach cancer patients should have a light diet, avoiding cold, oily, spicy, stimulating, dry and hard food, and at the same time, ensure sufficient nutrition. Mango is a fruit rich in vitamins, minerals, sugar and other nutrients. If there is no allergic reaction to mango in the past, stomach cancer patients can eat mango, which basically has no special effect on their condition. However, the nutrition of mango is not comprehensive, so it is better to consume it in moderation as a supplement to regular meals. However, if gastric cancer patients combine with gastrointestinal bleeding, perforation, obstruction and other conditions, they should follow the doctor’s instruction to abstain from eating for the time being. It is suggested that patients should choose appropriate treatment plan under the guidance of physicians, pay attention to rest and moderate activity in life.
